摘要: 为有效缓解陈四楼煤矿区域瓦斯含量高、存在突出危险等现状,对工作面煤体进行了水力冲孔卸压增透。重
点对该煤矿的水力冲孔卸压增透技术试验进行了探讨,得出了试验后的单孔抽采纯量。结果表明,抽采1 个月后日抽采
纯量从100 m3/d 提高到300 m3/d 左右,且4 个月内冲孔钻孔的抽采体积分数保持稳定在30%以上,有效提升了区域瓦斯
抽采效率。

Abstract: In order to effectively alleviate the present situation of high gas content and outburst danger in Chensilou Coal Mine,
the hydraulic punching pressure relief was carried out on the coal body of working face. This paper mainly discussed the experiment
of hydraulic punching pressure relief and permeability enhancement technology in the coal mine, and obtained the scalar
amount of single hole drainage after the test. The results showed that the daily drainage net volume was increased from 100 m3/d
to 300 m3/d after one month, and the drainage volume fraction of punching holes remained stable at more than 30% within 4
months, which effectively improved the regional gas drainage efficiency.

Key words: outburst prevention; hydraulic punching; pressure relief and permeability enhancement
